Air (ro = 1.23 kg/m^3, Mu = 1.79 x 10^-5 kg/m.s) flows through 4.0 mm diameter brass tube with velocity V=50m/s. Under these conditions flow is expected to be turbulent, but for a clean air, very smooth enterance (with guided vanes) to the tube and no tube vibration, it may be possible to maintain laminar flow. Determine the pressure drop in a 0.100m length assuming. a. Laminar Flow b. Turbulent flow.
Calculate the force (in Kn) a punch press must exert if it is to punch out a large washer from a strip of 5-mm thick sheet steel with an ultimate shear strength of 400 MPa. The washer dimensions are as follows: hole diameter is 27 mm. outside diam..
A tire carries a 5,000-lb load and has a pressure of 100 psi. The pavement has a modulus of elasticity of 43,500 psi. A deflection of 0.016 inches is observed at a point on the pavement surface 0.8 inches away from the tire load.
The concentration of trichloroethelyne (TCE) in an air sample near a hazardous waste landfill is 34 ppm, the ambient air temperature is 31 degrees C, and the atmospheric pressure is 0.94 atm. What is the TCE concentration in mg/m^3

You should provide the structural engineer with a formal typed report that will include all of your analyses and final size of the footing. You should also include all of your design assumptions in your report.
Air can be assumed as a di-atomic ideal gas. Find the final temperature and the amount of work ( in kW) required for air compression at a rate of 100 mol/s , from an initial condition of 1 bar an 25 C to 10 bar; for the following ways:
